提出了单相有源电力滤波器的一种新的计算方法 ,此方法可以使电源的输入功率因数接近于 1,且能保证即使在电源电压波形发生畸变时 ,能维持电源电流为正弦波。模拟实验证明 ,本文所提出的这种计算方法可以有效地起到补偿无功或抑制非线性负载谐波的作用
A new calculation method of single-phase active power filter is proposed, which can make the input power factor of the power supply close to 1, and can ensure the power supply current to be a sine wave even when the power supply voltage waveform is distorted. Simulation experiments show that the proposed method proposed in this paper can effectively compensate for reactive power or suppress the role of non-linear load harmonics
